I have a following python dictionary:

lines = {('mid', 'north'): None,

         ('south', 'mid'): None,

         ('south', 'north'): None,

        }

what I am trying to achieve is to get the first string or/and second string of one of the keys of the lines dictionary.

so lines.keys() gives me dict_keys([('mid', 'north'), ('south', 'mid'), ('south', 'north')])

what I would like to have is something like this:

lines.keys()[0][0]

'mid'

ofc it is not working like this but is there a function or a command which gives me the first string of the tuple ('mid', 'north'), as an output? Keep in mind ('mid', 'north') is the key of the dictionary.

You can convert dict_keys to tuple, since it is iterable:

>>> k = tuple(lines.keys())

>>> k[0][0]

'mid'

You need to convert your keys to list, and since dict will be in random order you need to sort it.

lines = {('mid', 'north'): None,

         ('south', 'mid'): None,

         ('south', 'north'): None,

        }



print(list(sorted(lines.keys()))[0][0]) # -> mid
